Abstract:
A pallet assembly is disclosed for use in simultaneous transfer of four preheated plastic preforms from an oven, through a blow mold where they are blown into bottles to a location where the bottles are discharged. The pallet has a base (shuttle) on which is mounted a plurality of pilot bushings for locating the pallet relative to the blow mold and other locations; four (one of each preform) preform registering means (locating and support assemblies), each to vertically locate and horizontally center each preform.
Abstract:
The apparatus comprises two superimposed conveyors the adjacent runs whereof move at the same speed in the same direction. The conveyors are provided with transverse guides on which sliding elements are mounted which provide support for the articles, in connection with the bottom conveyor, and clamp the articles against the underlying supporting elements, in connection with the top conveyor, the held articles being caused to advance past switches operated in succession to divert the articles along guide sets leading to respective removal belts.
Abstract:
An article carrier is provided for blow molding equipment which permits relatively simple exchange of the article gripping chuck portion of the carrier. The carrier includes a carrier body, a spindle rotatably supported by the body, an article gripping chuck removeably attached to the spindle and seals between the chuck and the spindle and between the chuck and a preform retained thereby. The chuck is provided with article gripping levers preferably rotatably supported by ball and socket joints. The levers have preform grasping projections at one end and first and second ball ends at the other end. The first ball end mates with the chuck body socket and the second ball end is engaged by a lever actuating ring slidably mounted on the outside of the chuck body.
Abstract:
An air conveyor for bottles and bottle preforms wherein bottles are preferably conveyed while supported from a neck ring intermediate neck and body portions of the bottle by air jets directed at the neck portion of the bottle from a plenum chamber defining a conveying path. The conveyor includes depending side curtains in close proximity to the sides of the bottles as an aid to conveyance. As a further aid to conveyance through inclined portions of the conveying path, the conveyor is provided with bottom plate joining the bottom edges of the side curtains.
Abstract:
A continuous belt conveyor for transporting bottles to be processed includes an inclined ramp portion for elevating bottles to a moving horizontal platform portion, screw means for selectively adjusting the height of the moving horizontal platform portion without varying the length or tension of the conveyor belt, a variable pitch horizontally disposed screw guide for uniformly spacing bottles as they enter upon the moving horizontal platform, and a plurality of uniformly spaced neck gripping overhead bottle carriers mounted on a continuous overhead chain moving in synchronism with the conveyor belt, with overhead cam means adjacent to the junction between the inclined ramp portion and the horizontal platform portion of the conveyor belt for causing the overhead bottle grippers to be successively elevated over, aligned with, and then lowered onto neck locking engagement with individual bottles passing therebeneath. The overhead bottle grippers comprise a clam shell type of structure opened when elevated and closed when lowered and a surrounding rotatable cylindrical shield which holds the clam shells in locked position when lowered thereover and which also by engagement with a suitable rack produces a rotation of the bottles as they are carried thereby through a spray processing station. A synchronous drive mechanism including a feedback loop between the conveyor belt and the overhead chain conveyor maintains constant speed and physical relationship between the two continuously moving conveyor means.
Abstract:
Glassware treating apparatus in which bottles which have been coated with a non-abrading coating are treated to remove surface irregularities in the coating on the bottom of the bottles. The bottles are gripped and suspended from conveyor means and pass consecutively over a heating zone, a cooling zone and a drying zone for removing the surface irregularities.
Abstract:
The disclosure relates to a machine for making a plastic covering on a rigid base article which in the illustrated form comprises a glass bottle and a conforming shrunken plastic covering thereon. The plastic is fed in oriented sheet form to the turret apparatus, cut into lengths and wrapped and seamed on successive mandrels as sleeves. Bottles are simultaneously processed to preheat condition and indexed over the sleeves, the latter telescopically assembled on the rigid base article, i.e. the bottle, and the combination carried to a heat tunnel. The plastic sleeve shrinks into snug surface fit on the adjacent surface portion of the rigid base article. The bottle is preheated in one of two embodiments by: (1) a preheat tunnel on the machine which raises the bottles from room temperature to about 220*F, or (2) the preheat is carried over as latent heat in the glass bottle from the annealing lehr, a part of the bottle manufacturing process. The machine includes novel subassemblies comprised of (1) a bottle chuck and loading station for assuring proper loading of the bottles on the machine, (2) bottle handling, (3) plastic strip handling and feed mechanism for placing oriented cut lengths onto mandrels of the turret, (4) the turret for making seamed sleeves in succession and feeding them onto registered bottles carried by the bottle handling apparatus, and (5) unloading device for transfer of the covered bottles to a conveyor and with said transfer smoothening the bottom surface of the covering on the bottle.
